    date5mb16a0 toshiba short circuit in the VIN line

    I have a problem on this motherboard. I have a short circuit in the VIN line (pq1 pin 4) as shown in the diagram. but I can't find the origin. inject 1v into the line, it goes up to 3A but in no sector and no component overheats. which may be? Could it be some internal clue?

      Check your jumper wire if consuming amp rather than shorted component
      If jumper wire getting heated than use a good gage wire in quality and thickness

          check the dc port its likely the culprit.. or internal component.. here is the schematics.. try to isolate the problem.. 1volt at 3amps is high and must give off heat.. try again.. check the dc port for heating..

                  Help me find the short circuit on this WORKING Nvidia GTX1650
                  by aaronkatrini
                  Hi all,

                  Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

                  Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

                  9th Gen Dell Optiplex Micro PC motherboard repair: Short Circuit?
                  by Geeker007
                  Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

                  I am new to electronics repair, so my queries could be naive but I am ready to learn.

                  So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...

                  Short Circuit tester
                  by Tarot Superstars
                  Hello.
                  I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
                  The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.

                  MSI B250 Gaming M3 Short circuit in CPU power supply circuit
                  by M1NEBLANK SHOW
                  Hello. MSI B250 Gaming M3 board, short-circuit on the power supply. Found a problematic mosfet VQ1
                  (N-PK616BA_PDFN8-HF) soldered it out - short circuit is gone. I replaced VQ1 + VQ5 (N-PK632BA_PDFN8-HF). VQ1 was replaced with PK618. After starting attempt VQ1 is lit again. What can be the problem? In the driver?

                  Fault source of a short circuit
                  by rumpumpel1
                  I have a mainboard with a short circuit (approx. 0 Ohm) on the 3.3V rail. As usual, I injected current and observed the mainboard with the thermal camera. Instead of individual components becoming warm, I observed that an area of several square centimeters became evenly warm from approx. 2A.
                  Has anyone ever seen anything like this? Is it possible that there is a short circuit between two layers of the mainboard? The visual inspection of the mainboard did not reveal any abnormalities....
